JAMES J. HARNSBERGER, OF DECATUR, ILLINOIS.

BELT-REPLACER.

SPECIFICATION forming part of Letters Patent No.315,615, dated April 14,1885.

' Application filed February 24, 1885. (No model.)

To all whom, it may concern.-

Be it known that I, James J. HARNSBER- GER, a resident of Decatur, inthe county of Macon and State of Illinois, have invented certain new anduseful Improvements in Belt- Replacers, of which the following is aspecification.

My invention consists in certain peculiarities of construction andcombinations of parts, as will be hereinafter set forth and claimed.

In the drawings accompanying and forming a part of this specification,Figure 1 represents the beginning, and Fig. 2 the completion, of theoperation of placing a belt on its pulley by means of my device. Fig. 3is a perspective representation of my device, and Fig. 4 an elevation ofcertain details of construction of the same.

a is a trip-lever that is operated by the belt for the purpose ofdisconnecting the replacer from the wheel. I) is a lever 'used to attachthe replacer to awheel or pulley. c is a hearing for the trip-lever a.(Z is a clamp-bar that reaches across the face of the pulley. e is anadjustable continuation of d. f is a pivoting clamp-jaw formed of thetermination of lever b. g is a plate-spring secured to the under surfaceof bar d. h is a clamp-jaw rigid on plate 6. t is a rod that passesthrough triplever d, and is adjustably connected with clamp-lever b.

It represents a parallel-surfaced formation of rod t, that enables thesame to be rotated with a wrench or with the fingers. Z isa por tion ofbearing 0 that acts as a rest for the end of rod '5. m in Fig. at is anut for rod i, pivoting loosely in lever b. n is the pulley-belt.

To place a belt on a pulley by means of my device, the belt is drawn upagainst the face of the pulley, substantially as shown in Fig. 1, andsecured in position by the clamps. The pulley is then rotatedsufficiently to carry the belt and replacer into the position indicatedin Fig. 2, when the said belt will operate the trip-lever of thereplacer and slip into position simultaneously. The rod 2' slidesloosely in lever to when unrestrained, and acts as a brace to holdclamp-jaw f against the rim of the pulley when said rod rests againststop Z, as shown in Fig. 3.

In securing the belt to the face of a pulley the end of rod is raisedclear of stop Z, and said rod permitted to slide through lever (6 untilclamp-jaw f is opened sufficiently to pass over the rim of the pulley.Lever Z) is then used to force said clamp into position under the rim ofthe pulley, and should rod 2' prove to be too short or too long to fitclosely against stop Zwhen the clamp is properly adjusted its length maybe modified by turning it and screwing the threaded end threugh nut m.

When the device is attached to the pulley, spring g is forced againstthe belt until it comes in contact with bar (l, and the function of saidspring is to assist the belt in throwing the replacer from the pulleywhen clamp f is released. The replacer may be adj ust-ed to accuratelyfit the rim of the pulley by means of the slots and bolts in plate 9.

As indicated in Fig. 4, lever to is recessed to receive the head of rod'Z, and this arrangement enables said rod to be readily adjusted againststop Z.

To enable the same trip-lever to be operated on pulleys having differentdiameters, a series of pivot-holes are provided both in the lever and inits bearing-frame c.

As represented in Fig. 2, the trip-lever is sufficiently elevated by thebelt to permit rod t to slide clear of stop Z, thereby disengagingclampf and permitting the belt, with the as sistance of spring 9, tothrow the device from the pulley.

It is obvious that the belt will trip the lever in passing onto thepulley, as indicated in Fig. 2, and at no other time, and thispeculiarity renders the operation of the rcplacer at all times effectiveand safe.

I claim as new and desire to secure by Letters Patent- 1. Thecombination, in a belt-replacer, of bar d, rigid jaw 7t, pivoting jaw f,lever b, brace-rod 2', stop Z, and a suitable trip-lever adapted to bethrown by the belt as it passes into positionon the pulley for thepurpose of disconnecting the replacer from the pulley, as set forth.

2. The combination, in a belt-replacer, of a clamp-bar provided with arigid jaw at one end and a pivoted jaw at the other, a clampleverconnected with the pivoted jaw, a brace to secure the pivoted jaw incontact with the rim of the pulley, anda trip-lever for thebraceadaptedto be operated by'thebeltfasit passes entirely on the pulley forthe purposeof disconnecting the replaeer from the pulley, as set 5forth.

3. The combination, in a belt-rep1acer, of clamp-bar (1, spring 9, rigidjaw h, piv ot'ing jaw f, lever b, brace-rod i, stop Z, and trip-1eyer a,all constructed and arranged to operate substantially as'and for thepurpose set forth. r'o In testimony whereof I sign my name in thepresence of two subscribing witnesses.
